Even after a good warm up pre run it takes me ages to really start to flow .
For the first 10 minutes it is a struggle - I've got the fitness and the motivation but my legs feel like cast iron and there is no flexibility in my style .
I generally grit my teeth and get on with it - however much I'd rather stop for a breather . Then at towards the end of my run I really feel brilliant.
Music can help at times but finding a tune to match your pace is important - slow jazz aint gonna help much if you want to go off like a rocket .
